Depends what you like. Personally I prefer home hospitality and getting a sense of how locals live in various Jewish communities when I travel, but Prague is probably most interesting to walk around if you don't mind eating in restaurants. The food is great and the restaurants are very nice. You'll be mostly with tourists, I'd imagine, but as far as ambiance you might like it better than the other places you mentioned.

I'll start.I was flying BA JFK to LHR. I wanted to get the front row seats so i told them I sprained my ankle, and they gave me the front row.When I was checking in they asked me if I needed a wheel chair, I told them I don't need one now but when I land I will take one. I totally forgot about it.

When I got off the plane there was a wheel chair waiting for me. I went in.

There was a huge customs line, they took me to the side and the agent just stamped my passport and let me right through.After the attendant brought me to baggage claim, i picked up my suitcase said thank you, gave him a tip and walked away.
